Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![O PRACTICING MAP SKILLS
Use Map 1-8: Africa to answer the following questions, Be sure always
to begin counting degrees of latitude from the Equator and degrees of
longitude from the Prime Meridian.
1. What body of water is located at 0° latitude, 0° longitude?
2. What body of water is located between 30°N and 40°N latitude?
3. What city is located near 30°S latitude, 30°E longitude?
4. In what country do the lines of 10°N latitude, 0° longitude cross?
5. In what country do the lines of 10°S latitude and 20°E longitude cross?
6. Write the approximate location of Cairo, Egypt, using latitude and
longitude. (Remember that the lines of latitude and longitude on this
map are spaced 10° apart. Give locations to the nearest degree.)
7. Write the approximate location of Kigali, Rwanda, using latitude and
longitude.
8. Write the approximate location of Cape Town, South Africa, using
latitude and longitude.
9. Write the approximate location of Abidjan, Côte d'Ivoire, using latitude
and longitude.
10. Write the approximate location of Freetown, Sierra Leone, using latitude
and longitude.
